Application of Digital Twins to Flexible Production Management: Taking a Shandong Factory as an Example

By enabling the merging of the virtual and real worlds, DT (Digital Twin) technology has considerably aided the development of businesses at both levels of digitization and networking in recent years. As an outcome, industrial research has shifted its attention to this new technology in the manufacturing business. However, there are still technical issues with DT technology, such as real-time data interaction, high integration of constituent elements, and high simulation. This paper proposes to solve these issues by presenting a framework that blends DT with 3D visualization technologies. A case study of an intelligent logistics management 3D scheduling system for a factory in Shandong verifies the applicability of digital twins to flexible production management. The example demonstrates that the framework can be synchronizing the virtual and real systems. Moreover, the framework can effectively cover the whole manufacturing life cycle, enhance production efficiency and product quality, and achieve flexible production management, helping the manufacturing industry's digital and intelligent transition.

Relations between the RSFSR and the Ukrainian SSR in the 1920s: diplomatic and administrative-institutional aspects

The article discusses the specifity of the relations between the RSFSR and the Ukrainian SSR in 1919–1929. The authors present the relations between the goverments of the two republics and actions of the Russian side aiming to transforme into the unitary state, initially rather loosely connected among them the constituent elements of the Soviet state. Relations between RSFSR and the Ukrainian SSR were burdened with significant disavantages from the very beginning, as the former appropriates the rights of the union center. The article explains also the role and the place of the permanent representations of the union republics in Moscow, as well as the influence of the commissioners (Ukrainian government representatives in Moscow) on Soviet Russia’s policy towards Ukraine. Permenent ignoring by the government in Moscow of Ukraine’s needs and expectations, prompted the leadership of the party and the government of Ukrainian SSR to seek protection of its economic interests at the institutional level. With the creation of the USSR, the legal status of the republics included in that state changed. Relations between the republics lost their interstate character. In place of the existing ones, new representations were established to ensure the maintenance of permanent ties between the government of the RSFSR and the governments of the union republics.

Numerical Approach in Superconductivity: An Advanced Study

The dependence of the critical temperature $T_c$ of high-temperature superconductors of various families on their composition and structure is proposed. A clear dependence of the critical temperature of high-temperature superconductors (hydrides, Hg- and Y-based cuprates) on the serial number of the constituent elements, their valence and crystal lattice structure has been revealed. For cuprates, it is shown that it is possible to obtain even higher temperatures of superconducting transitions at normal pressure by implanting mercury atoms into the crystal lattice of cuprate.

TEMBANG SANDUR BOJONEGORO: KEKERASAN BUDAYA DAN ARKEOLOGI-GENEALOGI PENGETAHUAN/ TEMBANG SANDUR BOJONEGORO: CULTURAL VIOLENCE AND ARCHEOLOGY-GENEALOGY OF KNOWLEDGE

AbstrakPenelitian sandur, kesenian rakyat berupa drama tari di Desa Ledok Kulon, Kecamatan Bojonegoro, Kabupaten Bojonegoro sudah banyak, tetapi yang membicarakan tentang kekerasan budaya dan tembang sandur dalam kerangka arkeologi dan genealogi pengetahuan belum ditemukan. Hal itu karena kekerasan budaya menimpa seni tersebut karena imbas stigmatisasi sepihak pascatahun 1965—1966 yang menganggap sebagai kesenian rakyat yang berafiliasi ke PKI, dan pada masa puritanisme Islam menguat pada tahun 1990-an yang menganggap sandur tidak sesuai dengan nilai-nilai Islam, padahal isi tembang-tembang sandur kontradiksi dengan stigma tersebut. Oleh karena itu, penelitian ini menguak aspek kekerasan budaya dengan menelusuri tembang sandur dari perspektif genealogi dan arkeologi pengetahuan dalam bingkai cultural studies. Teori yang digunakan adalah triangulasi teori, yaitu folklor, arkeo-genealogi pengetahuan, dan kesejarahan. Hasil penelitian ini menunjukkan bahwa (1) tembang-tembang sandur memiliki metrum puitika Jawa yang mengarah pada nyanyian anak-anak, dengan media bahasa Jawa lokal, dan menyimpan jejak kearifan lokal, etika, dan spiritual, (2) nilai-nilai Islam-Jawa menjadi ruh tembang-tembang sandur. Di dalamnya terdapat sinkretisme nilai-nilai Jawa dan Islam, (3) stigmatisasi sepihak pada Sandur Bojonegoro, baik oleh kalangan anti-komunis maupun puritanisme Islam, hanya melihat pada konteks kesejarahan Indonesia pada Orde Lama ketika politik menjadi panglima dan hanya melihat penampang permukaan semata tanpa mendalami unsur-unsur pembentuknya, ideologi, ajaran luhur, dan tradisi yang melahirkan seni sandur. Kata kunci:Sandur Bojonegoro, kekerasan budaya, arkeologi, genealogi pengetahuan AbstractThere are many researches on sandur, folk art in the form of dance dramas in Ledok Kulon Village, Bojonegoro District, Bojonegoro Regency, but those that talk about cultural violence and tembang sandurin the archaeological framework and genealogy of knowledge have not been found. This is because cultural violence befell the art because of the impact of unilateral stigmatization after 1965-1966 which considered it a folk art affiliated to the PKI, and during the period of strong Islamic puritanism in the 1990s, which considered sandur not in accordance with Islamic values, even though the contents tembang sandurcontradict this stigma. Therefore, this study uncovers aspects of cultural violence by tracing tembang sandurfrom the perspective of genealogy and knowledge archeology within the framework of cultural studies. The theory used is triangulation of folklore theory, archeology-genealogy of knowledge, and history. As a result, (1) the sandursongs have a Javanese poetic metre that leads to children's singing, with local Javanese language media, and keeps traces of local wisdom, ethics, and spirituality, (2) Javanese-Islamic values become the spirit of the tembang sandur. In it there is a syncretism of Javanese and Islamic values, (3) the unilateral stigmatization of SandurBojonegoro, both by anti-communists and Islamic puritans, only looks at the historical context of Indonesia in the Orde Lamawhen politics was the commander and only sees the surface without explore its constituent elements, ideology, noble teachings, and traditions that gave birth to the art of sandur.

Visual Behaviour and Cognitive Preferences of Users for Constituent Elements in Forest Landscape Spaces

Background: Elements of forest landscape spaces are important media through which landscape information is conveyed. Therefore, it is very important for designers and managers of forests to explore the relationship among visual behaviour, landscape preferences, and element characteristics. Purpose: This study took forest landscape spaces as the subject, discussed the characteristics of visual behaviour and cognitive preferences for landscape elements, and analysed the relationship among element characteristics, visual behaviour, and cognitive preferences in forest landscape spaces. The findings will help designers better plan the spatial composition of forest landscapes. Methods: We collected data from 53 graduate and undergraduate students and then used Spearman’s rho correlation analysis and multiple linear regressions to analyse the experimental data. Main results: 1. As the composition of forest landscape spaces varies and landscape elements are combined in different ways, visual behaviour towards landscape elements also differs. 2. People are easily attracted by highly fascinating landscape elements, but they will spend more time on low fascinating landscape elements. 3. Element characteristics significantly affect visual behaviour and cognitive preferences. Elements with high complexity or a large proportion of elements take more time for the participants to recognize, which reduces the evaluation of satisfaction.

Albanian Myths and Custom Law in Literature

Mythology plays a very important role in the general culture of the Albanian people, and the influence of the latter is undoubtedly seen in the later literature, developed in different historical periods, while mythology is taken as an important basis for a series of canons both in a structural manner as well as with the inclusion of a number of literary figures. Albanian mythology consists of a complete and diverse catalog of cults and beliefs which together have developed into a rich treasure which from time to time has inspired later Albanian writers, from the Middle Ages to modern ones. This article serves as pamphlet which explains the Albanian mythology in bold lines, including the main constituent elements of this mythology, the impact that this mythology has had on the daily customary life of the Albanian people, as well as the inevitable impact that the latter has had on the literature of the country.

THREE-DIMENSIONAL COMPUTATIONAL MODEL OF EARLY UPPER LIMB DEVELOPMENT

Limb development begins during embryogenesis when a series of biochemical interactions are triggered between a particular region of the mesoderm and the ectoderm. These processes affect the morphogenesis and growth of bones, joints, and all the other constituent elements of limbs; nevertheless, how the biochemical regulation affects mesenchymal condensation is not entirely clear. In this study, a three-dimensional computational model is designed to predict the appearance and location of the mesenchymal condensation in the stylopod and zeugopod; the biochemical events were described with reaction–diffusion equations that were solved using the finite elements method. The result of the gene expression in our model was consistent with the one reported in literature; the obtained patterns of Fgf8, Fgf10, and Wnt3a can predict the shape of the mesenchymal condensation of early upper limb development; the simple diffusive patterns of molecules were suitable to explain the areas where sox9 is expressed. Furthermore, our results suggest that the expression of Tgf-[Formula: see text] in the upper limb could be due to the inhibition of retinoic acid. These results suggest the importance of building computational scenarios where pathologies may be comprehensively examined.

Acoustic spaces of Fritz Kater’s dramatic collages

The article examines the GDR Trilogy by Fritz Kater as a dramatic collage, characterized by the multiplicity and heterogeneity of its constituent elements, re-coding the meanings of each fragment in the context of the whole, synthesis of various dramatic and epic techniques, elements of music, painting and other types of arts. The relations of connection, repulsion, parallelism, contrast that arise between the scenes in the context of the trilogy are traced. The authors strategy of constructing an auditory image in the play is described. On the example of the first of the plays Vineta or Vodomania / Vineta or Oderwassersucht, 2001), the author analyzes the sound score written in the authors remarks, emphasizing the division of the piece into two parts according to the principle of the golden section. The motive analysis used in the article shows how the extra-musical sound palette of the play, built in the spirit of John Cage, reveals and enhances the motive of loss the main motive of the first movement, and the silence that occurred in the last scenes helps to highlight the shame-motive that arises in them. Musical fragments of the play are associated with the mythological image of the sunken city, the lost paradise, the flourishing Vineta.
